12x12x48 tank of 33 gl. For LPG. Nice tank, used for about 6 years, installed new ( I am first owner) inside vapour box, inside my Pinzgauer 710K truck. It has a fuel gauge with a viewport and a sender to install an electric meter. This tank, I believe, was designed for a GM Suburban, but you may want to contact Sleegers engineering for specifics on installation, unless you just want to put in on your pickup bed, which is ideal. Let's talk about shipping if you are interested. I am willing to help out if you are not in a hurry to receive it.
